7962 cannot transfer from directory when second call arrives

[alessandro.dona]

    Hi to all,

i have a receptionist with a 7962 with a 4,3(maximum call,busy trigger).

She usually uses corporate directory to find number andf transfer call but if a secod call arrive when she is transefring the call the phone state "auto call disabled".

No problem if she enter the number without using directories.

I also changed autoline selection and auto call selection with no success.

Any idea abouti solving this issue?

Regards

Ale.
